System and method for multi server place data representation

ABSTRACT

Data on place objects in a distributed environment are generated in a system including a plurality of server objects instantiated in the environment in the same address domain, which share a same user directory and authentication system, are on a same user network, and are administered by a single administration team. A service catalog is provided for cataloging a plurality of place objects as nodes on a tree, place objects including the plurality of servers objects within the distributed environment. A document file is provided for encapsulating cataloged relationships of server objects in the distributed environment and for storing object attributes generated by traversing the tree.

BACKGROUND OF THE INVENTION

[0003] 1. Technical Field of the Invention

[0004] This invention relates to data processing in a distributed environment. More particularly, to a system and method for cataloging and traversing a plurality place objects within a distributed environment selectively to execute methods on said place objects, acquire data from said place objects for generating reports, and export that data into another distributed environment.

[0005] 2. Background Art

[0006] IBM Lotus Domino™ applications let people share, collect, track, and organize information, using Lotus Notes™ or the Web. Domino applications can cover a wide range of business solutions, including: workflow, tracking, collaboration, data integration, personalization, and globalization. Every Domino application contains one or more Domino databases. A Domino database is a container for the data, logic, and design elements in an application, and include: pages, forms, outlines, navigators, views, folders, framesets, shared resources, and agents. A page is a database design element that displays information. Forms, like pages, display information and can be used to collect information. Fields are the elements that collect data. A view is a sorted or categorized list of documents. A folder is a container that stores documents. An outline is a navigation tool created to customize a folder pane of an application. Navigators are graphical road maps that direct users to specific parts of a database, allowing users to find documents or take actions without having to open views. A frameset is a collection of independently scrollable frames. Agents are programs that perform a series of automated tasks according to a set schedule or at the request of a user. Shared resources are resources maintained in one standard place for use throughout the application, and include: image resources, shared fields, subforms, script libraries, shared Java files, and shared actions. Domino applications support collaboration, in which the unit of collaboration is a database.

[0007] Heretofore in IBM QuickPlace™ the unit of collaboration is a place which is a group of databases that reside on a single server. QuickPlace is implemented with an object model that includes four primary objects, including a (1) place that has (2) rooms which include (3) pages. And then there are (4) members of the place. Pages are organized within folders. Forms and fields are two further objects primarily visible to the designer of the place.

[0008] Place type is an object from which a place is created. Place type represents the foundation for building collaborative applications. Everything created in building collaboration space is done in a place. Once such a place is created, it can be made a template and copied as a place type. Once it becomes a place type, it is available for use by others for building additional places that include the format, look and feel, and other characteristics of the original place.

[0009] Other QuickPlace objects are skins and PlaceBots. Skins control everything about the user interface, including layout and style. Layout defines the positioning of components on the screen. Style defines the form and colors of those components. A PlaceBot is an enhanced agent, enhanced in the sense that it enables the use of Java or Lotus Notes or equivalent text editors. Once a PlaceBot is written using such an editor, and uploaded to a place, the server compiles the PlaceBot into an agent, reporting any errors. The agent resulting from a compiled PlaceBot can be scheduled to run at certain times, or upon opening a form. That is, the PlaceBot may be associated with a form, such as a sales order which, when opened, will cause the agent to execute. Thus, PlaceBots are the primary repository for custom logic in QuickPlace collaboration applications.

[0010] QuickPlace objects and equivalent Domino objects include the following: QuickPlace Server is equivalent to a Domino File Directory; Place to a File Directory; Page to a Data Note, Form & Subform; PlaceBot to a Domino Agent; Theme to a Data Note; Member to a Data Note in Contacts1.nsf; Subroom to a NSF Database; SubroomTheme to a Data Note; SubroomMember to a Data Note in Contacts1.nsf; Room to a NSF Database; Folder/TOC to a Folder or View; Form to a Data Note; and Field to a Data Note. Subrooms contain their own set of Folder, Page, Form, Field, PlaceBot & Subroom Objects.

[0011] In QuickPlace, version 1, administration was managed in server islands. It was not possible to get an overview of the QuickPlaces deployment in a large organization, and administration done in a large (many servers) deployment was tedious in that each server had to be managed individually without being able to generate reports that give the state of a plurality of places in an entire organization.

[0012] Programmatic administration of applications is known in, for example, a Domino environment. However, these do not understand the notion of QuickPlaces and the kinds of data relevant to such places, such as size, address, membership, last access, last modified, how distributed on servers, how places can be addressed through a URL, and ability to add meta data to each instance of the places (such as cost center, and other such user defined data).

[0013] There is a need to provide for scaling of the above QuickPlace collaboration model in several ways: 1) resource scalability, such as disk space, CPU, etc.; 2) geography scalability—which would allow deployments of places in different locations; and 3) administration scalability, with a multi-server unit of administration rather than having to administer a plurality of servers.

SUMMARY OF THE INVENTION

[0015] It is an object of the invention to provide a system and method for managing data and methods on a plurality of objects in a distributed environment.

[0016] In accordance with the present invention there is provided a system, method, and computer program product for representing data on place objects in a distributed environment by instantiating a plurality of servers in the environment; instantiating a service catalog to include indicia cataloging a plurality of place objects as nodes on a tree including the plurality of servers within the distributed environment; generating from the service catalog a document file encapsulating cataloged relationships of server objects in the distributed environment; traversing the tree to generate from the place objects a document file of object attributes; and generating from the document file reports including the object attributes.

BEST MODE FOR CARRYING OUT THE INVENTION

[0029] A QuickPlace service is a multi-server deployment of QuickPlace servers that can be treated as a consistent unit of service for administration and in the user interface.

[0030] A QuickPlace service comprises multiple QuickPlace servers and/or QuickPlace clusters, which: (1) are in the same Domino domain; (2) share the same user directory and authentication system; (3) are on the same user network (i.e., are not separated by a firewall); and (4) are administered by the same administration team.

[0031] These constraints are enough to ensure across the service that: (1) servers can be configured consistently; (2) servers can communicate and share data with each other; (3) user identities are in the same name space and do not collide; and (4) single sign on authentication can be implemented.

[0032] A QuickPlace cluster is treated as a single virtual server in the service model.

[0033] Referring to FIG. 1, catalog 120 is a database, such as a QuickPlace catalog, for aggregating information about projects, such as QuickPlaces 114, 132, 134, 136, in a multi-server system environment, including service 100/server 101, 122/123, 124/125, and 126/127. Host catalog server 280 is a Domino server with QuickPlace installed which has been configured to host catalog database 120 and which is accessible to QuickPlace servers 101, 123, 125 and 127 within a given service. Import/export tool 133 generates in intermediary file 135 a document containing a XML data representation of all places 114, 132 in a particular service, for example, 100/122. An example is the XML of Table 2. Document 135 is used, inter alia, to generate reports and to receive data exported from one service for importing into another service.

[0034] Throughout this specification, the generic term “project” and more specific terms “place” or “QuickPlace” are used substantially interchangeably. Place and QuickPlace are specific examples of projects.

Object Model

[0035] An object model is a collection of related objects. An object is a type of programming entity together with the properties of the entity and methods that perform actions on that entity.

[0036] A containment model provides a view of relationships of objects, and in effect culls out of an object model the specific relationships of its objects. Thus, a containment model specifies which objects hold other objects.

[0037] An inheritance model is a programming concept, or model, that illustrates how objects inherit. In object-oriented programming, subclasses (objects) inherit the non-private variables and methods of all their superclasses. That is, an object implicitly contains all the non-private variables of its superclass, and can invoke all the non-private methods of its superclass.

[0038] In accordance with the exemplary embodiment based on a QuickPlace environment, all object representations adhere to the QuickPlace Object DTD of Table 1.

[0039] A Document Type Definition (DTD) is written in a formal syntax that explains precisely which elements and entities may appear in a document and the elements' contents and attributes. Validating parsers compare document to their DTDs and list places where the document differs from constraints specified in the DTD. The program can then decide what it wants to do about violations. Validation is an optional step in processing XML.

[0040] Table 2 presents an XML document describing a particular configuration of objects in database 114 forming a project, or QuickPlace. In this case, the XML tree of lines 3-5 allows the building of a tree that illustrates the entire organization across a plurality of servers 101 in a service, or distributed environment. The terms “places” and “servers” provide a level of indirection that encapsulates groups of the same type. For example, “servers” encapsulates a group of individual servers, making it easier to treat them as a unit.

[0041] Referring to FIG. 2, a high level containment model representation of an exemplary embodiment of the invention is presented. Each box represents a unit that can be manipulated and used to retrieve and store data. Each object has several associated methods.

[0042] QP service 100 represents the service. A service is an object that signifies a group of servers in an organization. There is one instance of a service 100 for any group of servers comprising a distributed environment. Thus, a QuickPlace service is a multi-server deployment of QuickPlace servers that can be treated as a consistent unit of service for administration and in the user interface.

[0043] A QuickPlace service comprises multiple QuickPlace servers and/or QuickPlace clusters, which: (1) are in the same Domino domain; (2) share the same user directory and authentication system; (3) are on the same user network (i.e., are not separated by a firewall); and (4) are administered by the same administration team.

[0044] These constraints are enough to ensure across the service that: (1) servers can be configured consistently; (2) servers can communicate and share data with each other; (3) user identities are in the same name space and do not collide; and (4) single sign on authentication can be implemented.

[0045] A QuickPlace cluster is treated as a single virtual server in the service model.

[0046] Server 101 represents a physical or virtual server entity that is addressable and may contain a group of places 103 and place types 102.

[0047] Place 103 is an object that represents a place or project. This is the entry point into a particular project and all its data and all its manipulations—including logical methods such as lock, remove, member, and so forth.

[0048] QP members 104 represents members of place 114. There are many kinds of members, including person 115, local person 116, group 117 and local group 118. Members 104 are the seed of any membership operation done in the place 114. Each member 114 has an associated identity and profile. Member classes 115-118 map to classes 465-469, respectively, of FIG. 5.

[0049] Room 105 represents a room 113 within a project 114.

[0050] In an exemplary embodiment, a project is a place, which is content and membership associated with that content.

[0051] A room 105 controls access to a subset of the data in the project 114, including table of contents (TOC) 106, and folders 108.

[0052] TOC 106 represents the table of contents of a room 113, which is composed of many TOC entries 107, which TOC entry includes a url to a content and the associated type (folder, room, document, etc.) of that content.

[0053] Folder 108 contains many documents 109, and each room 113 can contain many folders 108.

[0054] Documents 109 represent documents in a place 114.

[0055] Each place 114 may contain many themes 110. A theme is an object that represents how to lay out the user interface for this project, and how to brand the user interface.

[0056] Layout 111 specifies one of the ways a theme 110 is laid out. Associated with each theme 110 there may be several layouts.

[0057] Session 112 is a session needed to work with this object model. It provides for associating an identity with any manipulation. For example, if when creating a place 114 on a server 119, session 112 represents the identity of the individual. If that individual does not have authorization to create a place 114, an error will be received.

[0058] Rooms 113 represent multiple rooms in a place 114.

[0059] Places 114 represents multiple places on a server 119.

[0060] Each object is able to represent itself as xml and recreate itself from the exported xml. Collectively, as will be apparent from context, the service, server, place, placetype, member, room, and document objects may be referred to as “place objects”.

Service Object 100

[0061] Service object, or node, 100 represents a container for one or more servers 119 that comprise the QuickPlace service. Servers that are part of a service can be manipulated with the following actions:

[0062] query

[0063] getplaces

[0064] getServers

[0065] search

[0066] <Query> queries QuickPlace service 100 for specific data. By providing a query capability at the service level, the administrator is able to retrieve specific information from one or more QuickPlaces 114 that are part of the service 100. Table 3 gives the syntax for the query action. TABLE 3 QUERY ACTION SYNTAX 1 Syntax 1: 2 <service action=“query”> 3   <query type=“get_member_places”> 4     <members> 5       <person> 6         . . . 7       </person> 8     </members> 9   </query> 10 </service> 11 Syntax 2: 12 <service action=“query”> 13   <query type=“ft_search”> 14     <query_string>properly formatted full-text 15     query</ query_string > 16   </query> 17 </service>

[0067] The <query> action node supports the following attributes:

[0068] Attribute Name: type

[0069] Supported Values:

[0070] “get_member_places”

[0071] Specifies whether or not the server is local to the executing XML script.

[0072] get_member_places

[0073] Given a member name, retrieves all places of the service of which that specified name is a member. Member places are listed by server name and server names are listed by service which is essentially all servers listed in the place catalog.

[0074] ft_search

[0075] Given a query string, retrieves all places in the Place Catalog that satisfy the conditions specified in the query

[0076] For each of the above query types, the results of the query are returned in the format of Table 4. TABLE 4 QUERY RESULTS SYNTAX 1 <servers> 2   <server> 3     <place> 4     </place> 5   </server> 6 </servers>

[0077] The getplaces action retrieves all places listed in the place catalog. Table 5 gives the syntax for the getplaces action. Places are listed by server name. The results of the query are returned in the format of Table 4. TABLE 5 GETPLACES ACTION SYNTAX <service action=”getPlaces”> </service>

[0078] The getservers action retrieves all QuickPlace servers listed in the place catalog. Places are listed by server name. The syntax for this action is:

[0079] Syntax: <service action=“getServers”>

[0080] The results of the getServers query are returned in the format of Table 6. TABLE 6 GETSERVERS QUERY RESULTS SYNTAX 1 <servers> 2 <server> 3 </server> 4 </servers>

[0081] The search action performs a “full-text” search across all QuickPlaces in the QuickPlace service. It returns an error action status if the QuickPlace configuration specifies that Search Places is disabled or if Search Places for Anonymous Users is disabled and the identity performing the search is anonymous. Table 7 sets forth the syntax and required XML for the search action. TABLE 7 SEARCH ACTION SYNTAX AND REQUIRED XML 1 Syntax: 2   <service action=”search” order=”1 | 2 | 3” start=”n” 3   count=”n”> 4     <query> 5       “Properly formatted full-text query string” 6     </query> 7 Required: 8   <service action=“search”> 9     <query order=“1 | 2 | 3”> 10     “Properly formatted full-text query string” 11     </query> 12   </service>

[0082] The criteria for the search are specified by the following attributes:

[0083] Attribute Name: type

[0084] Supported Values:

[0085] order A numeric value that specifies the search return sort order. The following values are supported:

[0086] 1 Return results sorted by relevance

[0087] 2 Return results sorted with oldest occurrences first

[0088] 3 Return results sorted with newest occurrences first

[0089] start Specifies the starting position of the search results to be returned. A value of zero is used if this attribute is not specified. A starting position of zero specifies that results starting with the first match should be returned.

[0090] count Specifies the maximum number of search match hits to be returned. A value of 15 is used if this attribute is not specified. A count of −1 specifies that the maximum number of hits should be returned.

Server Object 101

[0091] Server node 101 represents an installed QuickPlace server in the QuickPlace service 100. All actions performed on a QuickPlace server are executed from within the server node hierarchy. In the QuickPlace 3.0 release embodiment actions are performed only on the local server where the XML script 76 is executing. To perform actions on other servers in the service, the XML script is executed on each of the other servers. The server node supports the following actions:

[0092] getPlaceTypes

[0093] getPlaces

[0094] refreshPlaces

[0095] forceRefreshPlaces

[0096] upgradeAllPlacesAndPlaceTypes

[0106] <name>

[0107] <hostname>

[0108] <port>

[0109] <url_prefix>

[0110] The <name> element is used by the server node to specify the name of the server. The full canonical name or the abbreviated name of the Domino Server that this script is executing against may be specified. The name used is the name of the local Domino Server in which this script executes. Syntax of the <name> element is set forth in Table 8. The <name> element is required if<local=“true”> attribute is not specified or equals “false”. TABLE 8 SYNTAX OF NAME ELEMENT 1 <server> 2   <name>QPServer/ACME</name> 3 </server>

[0111] The <hostname> element is used by the server node to specify the host name that the script executes against. The name used should be an IP address or DNS resolvable host name. Syntax of the <hostname> element is set forth in Table 9. The <hostname> element is required if the <local=“true”> attribute is not specified or equals “false”. TABLE 9 SYNTAX OF HOSTNAME ELEMENT 1 <server> 2   <hostname>qpserver.acme.com</hostname> 3 </server>

[0112] The <port> element, which is optional, is used by the server node to specify the listening port of the server against which the script is executing. The syntax of the <port> element is set forth in Table 10. TABLE 10 SYNTAX OF THE PORT ELEMENT 1 <server> 2   <port>80</port> 3 </server>

[0113] The optional <url_prefix> element is used by the server node to specify the URL prefix to the hostname of the server executing the script. Its syntax is set forth in Table 11. TABLE 11 URL_PREFIX ELEMENT SYNTAX 1 <server> 2    <url_prefix>http://</url_prefix> 3 </server>

[0122] upgrade

[0123] getPlaceTypes retrieves all placetypes that exist on the specified server. The “standard” QP PlaceType is h_StdPlaceType. Placetypes are listed by server name. The syntax for getPlaceTypes is:

[0124] <server action=“getPlaceTypes”>

[0125] </server>

[0126] The results of the action are returned in the format of Table 12. GETPLACETYPES RESULTS FORMAT 1 <server> 2    <placetypes> 3       <placetype> 4          <placetype id=“8912471890219238”> 5          <name>ACMETeamPlacetype</name> 6          <description>The ACME Team's 7          Placetype</description> 8          <additional_information_url> 9             http://www.acme.com/acmeteaminfo 10          </additional_information_url> 11       </placetype> 12       . . . 13    </placetypes> 14 </server>

[0127] getPlaces retrieves all places that exist on the specified server. Places are listed by server name.

[0128] forceRefreshPlaces refreshes all places on the specified server from their respective placetypes. The refresh action occurs immediately. No action is performed if a place does not adhere to a placetype.

[0129] refreshPlaces refreshes all places on the specified server from their respective placetypes. The refresh action occurs at the next scheduled interval when the QuickPlace nightly maintenance process is run on the server. No action is performed if a place does not adhere to a placetype.

[0130] forceUpgradeAllPlacesAndPlaceTypes upgrades all places and placetypes on the specified server from a previous QuickPlace release. This action occurs immediately. The upgrade process involves refreshing the design of QuickPlace system files as well as the schema and design of user QuickPlaces. This action will forcibly invoke the upgrade process even if the places and placetypes on the server have already been upgraded.

[0131] upgradeAllPlacesAndPlaceTypes upgrades all places and placetypes on the specified server from a previous QuickPlace release. This action occurs immediately. If the server has already been upgraded then this action will have no effect. The upgrade process involves refreshing the design of QuickPlace system files as well as the schema and design of user QuickPlaces. This action will no effect if the places and placetypes on the server have already been upgraded.

[0132] forceupgrade upgrades the specified QuickPlace server from a previous release. This action occurs immediately. All core QuickPlace files are upgraded as well as the admin place if installed on the server. This action will forcibly invoke the upgrade process even if the server has already been upgraded.

[0133] upgrade upgrades the specified QuickPlace server from a previous release. This action occurs immediately. All core QuickPlace files are upgraded as well as the admin place if installed on the server. If the server has already been upgraded then this action will have no effect.

Place Object 103

[0134] Place node 103 represents a QuickPlace on the QuickPlace server 101 in the QuickPlace service 100. All actions performed on a place are executed from within the server node hierarchy.

[0135] The place node supports the following named elements:

[0136] <name>

[0137] <placetype>

[0138] The <name> element is required for all supported place actions (create, remove, etc.) It is used by the place node to specify the name of the place being serviced. This name refers to a place on the local server executing the script.

[0139] The <placetype> element is used by the place node to specify the placetype that is associated with the place being serviced. The placetype element is primarily used when creating and refreshing places. When performing operations involving a placetype, the user must previously define the place and assign it an idref id with the <link> element. The placetype is then referenced by the idref value later on in the script.

[0140] Place node 103 supports the following actions:

[0141] create

[0142] remove

[0143] forceRemove

[0144] update

[0145] lock

[0146] unlock

[0147] repair

[0148] refresh

[0149] forceRefresh

[0150] archive

[0151] registerInPlaceCatalog

[0152] unregisterInPlaceCatalog

[0153] register

[0154] unregister

[0155] changeHierarchy

[0156] sendDailyNewsLetter

[0157] sendWeeklyNewsLetter

[0158] sendMailToMembers

[0159] sendMailToManagersOnly

[0160] upgrade

[0161] forceupgrade

PlaceType Object 102

[0162] PlaceType node 102 represents a QuickPlace placetype on the QuickPlace server 101 in the QuickPlace service 100. All actions performed on a placetype are executed from within the server node hierarchy.

[0163] The placetype node supports the following named element:

[0164] <name>

[0165] which is required for all supported placetype actions. The <name> element is used by the <placetype> node to specify the name of the placetype being serviced. This name refers to a placetype on the local server executing the script.

[0166] Placetype supports the following actions:

[0167] refresh

[0168] forceRefresh

[0169] refreshChildPlaces

[0170] forceRefreshChildPlaces

[0171] upgrade

[0172] forceupgrade

[0173] remove

[0174] forceRemove

[0175] The refresh action refreshes the placetype specified by <name> on the server specified by <server>. If the placetype has already been refreshed then the operation will not occur. TABLE 13 REFRESH ACTION EXAMPLE 1 <service><servers> 2    <server local=“true”> 3       <placetype action=“refresh”> 4          <name>AcmeTeamPlaceType</name> 5       </placetype> 6    </server> 7 </servers></service>

[0176] The forceRefresh action refreshes the placetype specified by <name> on the server specified by <server>. If the placetype has already been refreshed then this action will force a refresh of the placetype. Table 14 provides an example. TABLE 14 FORCEREFRESH ACTION EXAMPLE 1 <service><servers> 2    <server local=“true”> 3       <placetype action=“forceRefresh”> 4          <name>AcmeTeamPlaceType</name> 5       </placetype> 6    </server> 7 </servers></service>

[0177] The refreshChildPlaces action refreshes the all derived children of the placetype specified by <name> on the server specified by <server>. If the child placetypes have already been refreshed then the operation will not occur. Table 15 is an example. TABLE 15 REFRESHCHILDPLACES ACTION EXAMPLE 1 <service><servers> 2    <server local=“true”> 3       <placetype action=“refreshChildPlaces”> 4          <name>AcmeTeamPlaceType</name> 5       </placetype> 6    </server> 7 </servers></service>

[0178] The forceRefreshChildPlaces action refreshes the all derived children of the placetype specified by <name> on the server specified by <server>. If the child placetypes have already been refreshed then refresh will occur regardless. Table 16 is an example. TABLE 16 FORCEREFRESHCHILDPLACES ACTION EXAMPLE 1 <service><servers> 2    <server local=“true”> 3       <placetype action= “forceRefreshChildPlaces”> 4          <name>AcmeTeamPlaceType</name> 5       </placetype> 6    </server> 7 </servers></service>

[0179] The remove action removes the specified placetype from the specified server. Removal of the placetype is performed when the QuickPlace Nightly maintenance process runs on the server. Table 17 is an example. TABLE 17 REMOVE ACTION EXAMPLE 1 <service><servers> 2    <server local=“true”> 3       <placetype action=“remove”> 4          <name>AcmeTeamPlaceType</name> 5       </placetype> 6    </server> 7 </servers></service>

[0180] The forceRemove action removes the specified placetype from the specified server. Removal of the placetype is performed immediately.

[0181] The upgrade action upgrades the specified placetype on the specified server from a previous version of QuickPlace. This action occurs immediately. The specified placetype is locked during the upgrade process. If the specified placetype has already been upgraded then this action will have no effect.

[0182] The forceupgrade action upgrades the specified placetype on the specified server from a previous version of QuickPlace. This action occurs immediately. The specified placetype is locked during the upgrade process. If the specified placetype has already been upgraded then this action will force another upgrade of the placetype regardless.

Person Object 115

[0183] Person node 115 represents a person on the QuickPlace server 101 in the QuickPlace service 100.

[0184] The <person> node 115 supports the following attributes:

[0185] local

[0186] subscribed_to_newsletter

[0187] subscribed_to_calendar_events

[0188] using_accessible_ui

[0189] email_client

[0190] The local attribute specifies whether or not the person is local to the specified place XML script. A value of “true” indicates that the person exists only in the specified place. A value of “false” indicates that the person exists externally to the specified place.

[0191] The subscribed_to_newsletter attribute specifies whether or not the person subscribed to the place's newsletter.

[0192] The subscribed_to_calender_events attribute specifies whether or not the person subscribed to the calendar events in the specified place.

[0193] The using_accessible_ui attribute specifies whether or not the person is using an accessibility user interface in the specified place.

[0194] The email_client attribute specifies which email client the person uses.

Person Node Named Elements

[0195] The person node supports the following named elements:

[0196] <dn>

[0197] <username>

[0198] <first_name>

[0199] <last_name>

[0200] <password>

[0201] <phone_number>

[0202] <offline_password>

[0203] <description>

[0204] <email>

[0205] <theme>

[0206] The distinguished name <dn> element is required for all supported place actions (create, remove, etc.) if operating on an external user. It is used by the person node to specify the external name of the person being serviced. This name refers to a person in a directory external to QuickPlace. This element is not specified when operating on a person that is local to the specified place

[0207] The <username> element is used by the person node to specify the person that is associated with the operation being performed. The value specified by this element represents a local user of the specified place. A local user is one that exists purely in the place and not in an external entity such as a directory. To specify an external user then the <dn> element described above is used.

[0208] The <password> element requires that the person attribute local=“true” be specified. The <password> element is used by the person node to specify the password of the person that is associated with the operation being performed. The value specified by this element represents the password of a local user of the specified place. This password is required when the specified user authenticates with the place. This element is not applicable when the <dn> element is specified.

[0209] The <offline_password> element is used by the person node to specify the offline password of the person that is associated with the operation being performed. This password is used when the person authenticates with the place in offline mode. The value specified by this element can be used with either a local person or an external person.

[0210] The <theme> element is used by the person node to specify the name of the theme, or skin, associated with the operation being performed. The value specified by this element can be used with either a local person or an external person.

Person Node Actions

[0211] Person node 115 supports the following actions:

[0212] add

[0213] remove

[0214] update

[0215] rename

[0216] The add action adds a person to the specified place. The person may exist locally to the place or may exist externally to the place in an external directory depending upon which attribute is specified for the person (see above). When adding an external person to a place, the external directory is not consulted for existence or name correctness. Any supported attributes or elements of the person can be specified when the add action is performed since the specified person is updated immediately following this add operation.

[0217] The add action is performed to initially add a person to the specified place but it does not give that person any rights to access elements of the place. That action is performed by the <member> node. Table 18 illustrates an example of the add action. TABLE 18 EXAMPLE PERSON NODE ADD ACTION 1 <service> 2    <servers> 3       <server> 4          <name>QPServer/ACME</name> 5          <hostname>qp.acme.com</hostname> 6          <port>80</port> 7          <places> 8             <place> 9                <name>ACME_Team</name> 10                <members> 11                   <person local=“true” 12                   action=“add”> 13                      <username >Jane 14                      Doe</username> 15                      <password>BigSecret 16                      </password> 17                      <first_name>Jane 18                      </first_name> 19                      <last_name>Doe                      </last_name> 20                </person> 21                <person action=“add”> 22                   <dn>cn=Charles Brown, 23                   ou= Sales, o=ACME </dn> 24                </person> 25                </members> 26             </place> 27          </places> 28       </server> 29    </servers> 30 </service>

[0218] The remove action removes a person from the specified place. The person may exist locally to the place or may exist externally to the place in an external directory depending upon which attribute is specified for the person (see above). Removing a local person removes that person from the specified place. Removing an external person removes that person from the place but not the external directory.

[0219] When a person is removed from a place, his access to all rooms in the place is also removed.

[0220] The update action updates a person in the specified place. When this action is called, the specified person is updated using the attributes and values specified. Any supported attributes or elements of the person may be specified when the update action is performed. No updates are performed in the external directory.

[0221] The rename action renames a person in the specified place. When this action is called, the specified person name is updated to the value specified. All other attributes of the person remain the same after the rename process. The person information in the external directory is not updated by this action. That must be done in a separate process outside of this script.

Group Object 117

[0222] Group (external) node 117 represents a group on the QuickPlace server 101 in the QuickPlace service 100. All actions performed on a group are executed from within the place node hierarchy. Group operations are performed on groups that have identities in external directories. (Local groups 118 are groups that exist purely in the place.) Group 117 supports the following actions:

[0223] add

[0224] remove

[0225] update

[0226] rename

Member Object 104

[0227] Member node 104 (inside room managers, readers and authors) represents a member of one or more rooms 113 in a specified place 114 on QuickPlace server 119 in QuickPlace service 100. All actions performed on a member 104 are executed from within the <room> node hierarchy 113. The member node 104 is primarily used to define, modify, or remove membership access to one or more rooms in the place 114. When performing actions on a member, a person 115, 116 or group 117, 118 that represents the member must have been previously defined in the script. Operations on a member node 104 are performed using an idref link to the person or group nodes previously defined in the script. An idref link relationship is illustrated in Table 19. Member 104 supports add, remove, and rename actions. TABLE 19 IDREF LINK RELATIONSHIP ILLUSTRATION 1 <members> 2    <person local=“true” id=“person1”> 3       <username>jdoe</username> 4    </person> 5    <person id=“person2”> 6       <dn>cn=Charles Brown,ou=Sales,o=ACME</dn> 7    </person> 8 </members> 9 <rooms> 10    <room> 11       <name>Main.nsf</name> 12          <access> 13             <managers> 14                <member action=“add”> 15                   <link idref=“person1”/> 16                </member> 17             </managers> 18             <authors> 19                <member action=“remove”> 20                   <link idref=“person2”/> 21                </member> 22             </authors> 23          </access> 24    </room> 25 </rooms>

[0228] The <person> node is defined first with a corresponding link ID value. That ID value is referenced through the <link idref> element to determine which <person> the <member> node should operate on.

[0229] The major distinction between a <person> or <group> and a <member> is that a <person> or <group> represents an entity that the place has information about. A<member> represents a <person> or <group> node's access or membership to a particular room.

[0230] Referring to FIG. 3, host catalog server 280 is a Domino server with QuickPlace installed which has been configured as is represented by line 336 to host catalog database 120 and which is accessible as is represented by lines 300, 302 to QuickPlace servers 101 in the enterprise through the IBM® Lotus® Notes® RPC (tcp port 1352) and http protocols. A typical project, or QuickPlace, cluster 318 includes a load balancer (LB) LB1 server 312, a plurality of other servers 314, 136, and respective project databases 320, 322. A project cluster 318 is treated as a single virtual server in the service model.

[0231] Some entries 331-334, 341-345 are created or updated in the Host catalog 120 in real time—substantially the moment an event happens. Other entries are created or updated manually by a server task, or on a scheduled basis.

[0232] As is represented by line 300, it is essential that certain data be sent in real time to avoid conflicts. For example, in a QuickPlace service 100 there cannot be two places 114, 139 with the same name. The creation of a new place 139 is an event that creates a new entry in Catalog 120 in real time. When a user creates a new place, QuickPlace server 101 first checks catalog 120 database 129 for that name 323 before creating a new entry. If it finds an existing place with that name, the user is prompted to choose a different name. If the creation of a place 139 did not immediately create an entry, it would be possible for two users to successfully create two places with the same name, which would cause a conflict when QuickPlace attempted to create entries for both in the catalog 120. To increase availability of host catalog 120, the Domino clustering feature can be used to make several host catalog servers 280 available.

[0233] Data can be updated in catalog 120 using a QPTool placecatalog-push command or on a schedule on the QuickPlace server 101.

[0234] Host catalog 120 contains information in servers view 127 about servers and in places view 129 about places. Thus, in host catalog 120, there is an entry 331 for server of name 324 A 101, together with entries 326 and 328 identifying whether or note server A 101 is a virtual or master server, respectively. For simple case aggregation, or data update, projects 114, 139 are preconfigured as is represented by lines 300,338 to point to host catalog server 280 immediately when changes occur, or as is represented by line 302 at a particular time (say, each day at 2:00 a.m.) Immediate changes may thus be made when change actions occur such as place create, place remove, place lock, change access (add/remove readers, authors, managers), and change title. Scheduled updates may be made, for example, for changes such as last modified, title, size, last accessed.

[0235] Complex aggregation is required when working with clusters 318.

[0236] Each entry in catalog 120 has a virtual indicia entry 325, 326 and master indicia entry 328, 327. A master entry, such as entry 343, is the entry through which all access to the catalog occur for a given cluster of servers 312, 314, 316. In FIG. 3, servers A 101 and LB1 312 are master servers, and columns 327 and 328 are set for corresponding entries 331, 334, and 341-343. Each place 323 is identified as to its server 329.

[0237] A virtual server is a server that does not have project (such as, place) data, but knows how to connect place users to the project servers 314, 316 which do have place data 320, 322. Server LB1 312 is a virtual server because it does not have place data in a database. Project servers A 101, B 314, and C 316 are not virtual servers because they do have place data in databases X 114, Y 139, and Z 320, 322. Databases Z 320, 322 are clustered, so they are identical; a change to one is immediately replicated to the other.

[0238] Complex aggregation for clusters is done by sending immediate updates as are represented by lines 304 and 306 to master entries 334, 343. All other updates are sent, as are represented by lines 308 and 310, to the corresponding place entry 344, 345 for the respective servers B 314, C 316. For scheduled update, host catalog server 280 executes a process to merge entries from the virtual master LB1 312 (see entry 343, which has virtual field 235 and master field 327 set) to merge entries from the virtual master entry 343 to entries 344, 345 for other servers B 314, C 316.

[0239] The Host catalog feature is enabled by the administrator creating a host catalog database 120 and a configuration file.

[0240] Host catalog 120 may be created by using a PlaceCatalog.ntf template to create a Notes database. The template is put in the Domino data directory where QuickPlace is installed. Access control on catalog 120 is granted only to all the project servers 101, etc. and to administrators of the system.

[0241] The PlaceCatalog feature is configured for each server 101, etc., that interacts with PlaceCatalog server 280 through a configuration file formatted as xml. That is, each QuickPlace server 101, etc., that wishes to operate with a PlaceCatalog 120 must have its own configuration file. The name of the file is qpconfig.xml, and is set forth in Table 20. TABLE 20 PLACE SERVER CONFIGURATION FILE FOR CLUSTERING (qpconfig.xml) 1 <?xml version=“1.0” standalone=“yes”?> 2 <server_settings> 3  <place_catalog_settings enabled=“true”> 4   <log_level>4</log_level> 5   <domino_server_name>cat1/acme</domino_server_name> 6   <nsf_filename>PlaceCatalog.nsf</nsf_filename> 7  </place_catalog_settings> 8  <cluster_settings> 9   <master virtual=“true”> 10    <hostname>qp.acme.com</hostname> 11   </master> 12  </cluster_settings> 13 </server_settings>

[0242] Cluster_settings (Table 20, lines 8-12) contains settings related to the clustering feature as it relates to the server associated with this configuration file. The PlaceCatalog understands the clustering configuration so it can make the proper decisions when registering places with the Host catalog. This cluster_settings section includes the following:

[0243] 1. Master

[0244] In QuickPlace clustering there is a concept of a “master” server 312. It specifies which server in the cluster 318 acts as the “entry point” to a QuickPlace 320, 322. It can be a QuickPlace server or it can be a network dispatcher which acts as a “virtual” server. The following argument is available in this section:

[0245] virtual=“yes”

[0246] virtual=“no” (default)

[0247] which specifies if the master server is a device other than a QuickPlace server such as a network dispatcher or local director 312. Master includes:

[0248] 2. Hostname

[0249] which specifies the hostname in tcpip format of the master server 312 in a QuickPlace cluster 318 (i.e. qp.acme.com). This is the host name of a network dispatcher or local director (virtual must be “yes” above) or the hostname of a QuickPlace server (virtual must be “no” above)

[0250] Each time a place is created, it is registered in real-time with host catalog server 280. This means that PlaceCatalog 120 is configured on a QuickPlace server 101, and the host catalog server 280 must be operational for users to be able to create places.

[0251] When a QuickPlace manager adds, removes or changes a member's access level, an update is done to host catalog 120.

[0252] Host catalog 120 may be queried to retrieve a list of places 114 in which a user, or one of the groups 117, 118 of which the user is a member 104, 116, is a member 104.

[0253] When a user performs a search scoped to a number of QuickPlaces 114, 139, 320, 322 on one or more servers 101, 312, the system uses a search domain server to perform the search and it also uses the host catalog server 280 to properly construct the URLs to the places found in the search request. For this reason, the search domain server (not separately shown, but similar to server 101) is configured to recognize host catalog server 280.

[0254] Last accessed updates may be made in real time (say, every 1 minute) to host catalog 120.

[0255] Certain information maintained in host catalog 120 may not updated in real-time. Examples include place size and the last time it was accessed or modified. This information must be updated in batch mode. This is accomplished by running a qptool utility function “UpdatePlaceCatalog” on, for example, a daily basis. This can be automated as a Domino program entry similar to the QuickPlaceNightly tool.

[0256] When using QuickPlace clusters 318, host catalog 120 data is maintained for each node 312, 314, 316 in the cluster as well as for a virtual place representing the combination of all nodes if and only if a network dispatcher or local director has been configured and the proper settings reflect it in the qpconfig.xml configuration file. In this case, real-time updates to the catalog are done to the virtual place entry 343 and the non-real time updates are done to each of the cluster node entries 344, 345. This allows the administrator flexibility in knowing differences in access and size for each of the nodes in the cluster.

[0257] The last accessed time updates may present a problem in large installations. For this reason, a replica of the Host catalog 120 may be created for each QuickPlace server 101.

[0258] There are two QuickPlace server cluster environment alternatives for storing QuickPlace server cluster data in Host catalog 120.

[0259] 1. If cluster 318 does not have a virtual server 312, data is maintained in separate entries in host catalog 120 for each physical server 314, 316, and for each place 320, 322 on a physical server.

[0260] 2. If cluster 318 has a virtual server 312, each physical server 314, 316 and place 320, 322 has an entry 344, 345, respectively. But there is also an entry 343 for the virtual server 312 that represents the combination of all physical servers. And there is an entry for each place in the cluster that represents all the replicas of the place in the cluster. When the cluster has a virtual server 312, real-time updates to host catalog 120 (such as place creation, locking of a place, and place membership changes) are made in place entries 334, 343 corresponding to the virtual server. The non-real time updates (such as place size, time last accessed, and time last modified) are made to the place entries 344, 345 corresponding to the physical servers 314, 316 in the cluster. This information allows the administrator to know the differences in access 399 and size 349 for the places 320, 322 in each of the physical servers 314, 316 in the cluster 318.

[0261] A QPTool placecatalog command with the -update flag set synchronizes the place entries 344, 345 that correspond to the physical servers 314, 316, and the place entries 343 that correspond to the virtual server 312.

[0262] To set up a virtual server 312 for a QuickPlace cluster 318, a network dispatcher is configured, such as IBM Network Dispatcher Version 3.6, with proper settings configured on each server 312, 314, 316 in the cluster 318.

[0263] Referring to FIG. 4, XML 70 input 86 to and XML 72 output 87 from the APIs perform multiple actions in one call. Table 21 illustrates an example input tree, or document, 70, and Table 22 an example output document, or resultant tree, 72. Input data 86 for all APIs are the same. That is, the same object representation is used across all APIs. As is represented by reentrant line 89, input and output of an API call can be the input to another, and error and status indications are returned and maintained for each action. Reentrant path 89 provides for processing output document 72 through engine 76 if an error is found in input 86 or if new script is generated in output 87. In the later case, engine 76 is used to generate new programs 72 out of input programs 70. The methods are extensible to add support for new actions, support for multiple servers, including multiple servers within a service, and support for the ability to impersonate a person. Resultant tree 72 can be reinvoked, as is represented by reentrant path 89, selectively to generate new trees with or without action and, if there were errors, to rerun. During the rerun, engine 76 will start where it left off and process only those nodes that failed, and children of those nodes.

[0264] XML is created to represent, for example, a QuickPlace object. Each API capable object has an action attribute associated with it. This action attribute represents the API to be invoked. The XML 70 is passed into a Java method 76, which then processes the XML and returns an updated form 72 of the input XML 70. Upon completion, XML 72 similar to the input XML 70 is returned. TABLE 21 EXAMPLE INPUT DOCUMENT (TREE 70) 1 <service><servers> 2    <server local = “true” 3    <places> 4       <place action = “lock”> 5          <name>haikuteam</name> 6       </place> 7    </places> 8    </server> 9 </servers></service>

[0265] The XML of Table 21 is used to lock the place haikuteam on the local server. After the lock API is invoked the XML of Table 22 is returned. TABLE 22 EXAMPLE OUTPUT DOCUMENT (RESULTANT TREE 72) 1 <service><servers> 2    <server local = “true”> 3    <places> 4       <place> 5          <name>haikuteam</name> 6          <action_result action = “create”> 7             <status>0</status> 8          </action_result> 9       </place> 10    </places> 11    </server> 12 </servers></service>

[0266] When an action is executed on a QuickPlace object, a child node is created with the action status. This status represents if the action was successful through the returned status code in the action_result node.

[0267] To run the XML API as a person, a separate piece of XML is passed into the API. This XML identifies a given person's identity. The default person is the local server. An example of a session is provided in Table 23. TABLE 23 EXAMPLE SESSION RUNNING XML API AS A PERSON 1 <session> 2    <person> 3       <dn>CN=Sami Shalabi, OU=Westford, O=IBM</dn> 4    </person> 5 </session>

[0268] If API 76 uses this session XML, the actions are invoked using the identifier

[0269] “CN=Sami Shalabi,OU=Westford,O=IBM”.

[0270] Representing and manipulating place data is accomplished through the object model represented by the hierarchy of FIGS. 5 and 6.

[0271] Referring to FIGS. 5 and 6, Java class objects implementing the system and method of the preferred embodiments of the invention for programmatically representing and manipulating place data across a service are shown, and described in the tables which follow.

[0272] In FIG. 6, each object has a set of methods than can be invoked upon it. The containment model of this FIG. 6, therefore, shows the way objects are traversed, that is searched or identified, in order to reach properties (that is, invoke methods to retrieve data). For example, to get to placetype 487, processing must go from service 475 to servers 485 to server 474. Examples of data in FIG. 6 are name 491, hostname 493, port 495, name 497, description 499, additional_information_url 501, name 503, and name 505. To get to server name 491, processing goes from service 475 to servers 485 to find server 474 or 483 with name 491. This shows how objects relate to each other; that is, service 475 contains server 485, which contains one or more servers 474, 483, and so on. Objects contain properties of two types: straight properties and objects. Straight properties, or data, of server 474 are illustrated by name 491, hostname 493 and port 495. Properties which are objects are illustrated by placetypes 487; these objects are leafs in the tree which continue to grow (in this case, extending to placetype 479 and so on). The objects servers 485, placetypes 487, and places 489 provide a level of indirection that encapsulates groups of the same type. For example, servers 485 encapsulates a group of individual servers 474, 483, making it easier to treat them as a unit.

[0273] In FIG. 6, every node that is an object has a set of methods that can be invoked on that object. FIG. 6, therefore, represents a containment model which illustrates how objects are traversed, searched, or identified, in order to invoke methods on them. This also is a data representation, in that it shows how objects are traversed, searched or identified, in order to get to its data. This model, therefore, supports in a distributed environment, or service, the generating of reports with respect to a service, and the exporting of data from one distributed environment into another; and the traversing of a tree of objects within a service, or distributed environment, to access a predetermined node for executing supported methods on an object.

[0274] In FIG. 5, the object model of FIG. 6 is represented as XML—a list of objects and how they inherit. If the properties 491, 493, 495, 497, 499 501, 503, and 505 were removed from FIG. 6 the result would show the relationships of objects inside of the programming model of FIG. 2. This FIG. 5 shows how child objects inherit from, or extend, their parents.

[0275] The methods and instance variables for selected class objects in the hierarchy of Table 1 and FIGS. 5 and 6 are as follows.
